Definitions

  • the present invention relates to the therapeutic use of quinolone derivatives, and to certain novel such compounds.
  • Quinolone compounds are known primarily as antibacterial agents (see JP-A- 05025162; US-A-5037834; EP-A-0420069; WO-A-9410163; JP-A-02040379; EP-A- 0343560; DE-A-3816119; EP-A-0304158; and DE-A-3641312) or antiviral agents (US-A-4959363) but also as inhibitors of 5-lipoxygenase (JP-A-02124871), cardiotonics and vasodilators (JP-A-01061461) and 5-HT 3 antagonists for the treatment of peripheral disorders associated with pain (WO-A-9501793 and GB-A-2236751). None of these publications discloses utility as PDE IV inhibitors.
  • Phosphodiesterases regulate cyclic AMP/ GMP concentrations.
  • Phosphodiesterase IV has been demonstrated to be a principal regulator of cyclic AMP in respiratory smooth muscle and inflammatory cells [see Torphy and Cieslinski, Molecular Pharmacology 37:206 (1990); Dent et al, British Journal of Pharmacology, 90:163p (1990)].
  • Inhibitors of phosphodiesterase IV have been implicated as being bronchodilators and asthma-prophylactic agents, as agents for inhibiting eosinophil accumulation and the function of eosinophils [see for example Gembycz and Dent, Clinical and Experimental Allergy 22:337 (1992)] and for treating other diseases and conditions characterised by, or having an etiology including, morbid eosinophil accumulation.
  • Inhibitors of PDE IV are also implicated in treating inflammatory diseases, proliferative skin disease and conditions associated with cerebral metabolic inhibition.
  • Tumour Necrosis Factor is a serum glycoprotein.
  • TNF production has been implicated in mediating or exacerbating a number of diseases including rheumatoid arthritis, rheumatoid spondylitis, osteoarthritis, gouty arthritis and other arthritic conditions; sepsis, septic shock, endotoxic shock, gram negative sepsis, toxic shock syndrome, adult respiratory distress syndrome, cerebral malaria, chronic pulmonary inflammatory disease, silicosis, pulmonary sarcoidosis, bone resorption diseases, reperfusion injury, graft vs.
  • allograft rejections fever and myalgias due to infection, such as influenza, cachexia secondary to infection or malignancy, cachexia secondary to human acquired immune deficiency syndrome (AIDS), AIDS, ARC (AIDS-related complex), keloid formation, scar tissue formation, Crohn's disease, ulcerative colitis, or pyresis, in addition to a number of autoimmune diseases, such as multiple sclerosis, autoimmune diabetes and systemic lupus erythematosis.
  • AIDS acquired immune deficiency syndrome
  • AIDS AIDS
  • ARC AIDS-related complex
  • keloid formation scar tissue formation
  • Crohn's disease Crohn's disease
  • ulcerative colitis ulcerative colitis
  • pyresis in addition to a number of autoimmune diseases, such as multiple sclerosis, autoimmune diabetes and systemic lupus erythematosis.
  • HIV Human Immunodeficiency Virus
  • HIV-l HIV-l
  • HIV-2 HIV-3
  • HIV-3 HIV-cell mediated immunity
  • infected individuals manifest severe opportunistic infections and/or unusual neoplasms.
  • HIV entry into the T lymphocyte requires T lymphocyte activation.
  • Viruses such as HIV-l or HIV-2 infect T lymphocytes after T cell activation and such virus protein expression and/or replication is mediated or maintained by such T cell activation. Once an activated T lymphocyte is infected with HIV, the T lymphocyte must continue to be maintained in an activated state to permit HIV gene expression and/or HIV replication.
  • Cytokines are implicated in activated T-cell mediated HIV protein expression and/or virus replication by playing a role in maintaining T lymphocyte activation. Therefore, interference with cytokine activity such as by inhibition of cytokine production, notably TNF, in an HlV-infected individual aids in limiting the maintenance of T cell activation, thereby reducing the progression of HTV infectivity to previously uninfected cells which results in a slowing or elimination of the progression of immune dysfunction caused by HIV infection.
  • Monocytes, macrophages, and related cells, such as Kupffer and glial cells have also been implicated in maintenance of the HIV infection.
  • TNF cytomegalovirus
  • TNF is also associated with yeast and fungal infections. Specifically, Candida albicans has been shown to induce TNF production in vitro in human monocytes and namral killer cells. [See Riipi et al, Infection and Immunity, 58(9):2750-54 (1990); and Jafari et al, Journal of Infectious Diseases, 164:389-95 (1991). See also Wasan et al, Antimicrobial Agents and Chemotherapy, 35(10):2046-48, (1991); and Luke et al, Journal of Infectious Diseases, 162:211-214, (1990)]. The ability to control the adverse effects of TNF is furthered by the use of the compounds which inhibit TNF in mammals who are in need of such use.
